Dental implants act as a bridge between the oral environment and deep core structures of the jaw. The temperature rise leading to heat generation in the course of operation of the dental implants results in thermal injury of the adjoining bone tissue to the implant site resulting into implant failure. Present review is focused on existing research done in the heat generation and its distribution during dental implant drilling. Various factors such as drill speed, drill design, mode of irrigation, depth of drill, drill diameter, drill material that affect osseointegration due to heat generated while drilling, are compared. The motive of this review is to assess the various factors that are responsible for heat generation and their effects on osseointegration during osteotomy. A systematic study reveals that the rise in the temperature at the implant site mainly depends upon the drill speed, drill diameter, depth of drill as well as irrigation used. The purpose of this review is taking these factors into consideration to find out the best possible parameters during implantation to avoid bone necrosis. The temperature during dental implantation ranges from 35 ℃ to 43 ℃ while in some in-vitro studies the temperature increases up to 50 ℃ was observed which is not admissible due to the thermally induced necrosis. © 2022
